HD Radio in Canada is authorized through experimental licenses. Although all three of Canada’s major group owners – Corus, Bell and Rogers – have taken advantage of the technology, Innovation, Science, and Economic Development Canada (ISED) has yet to formally adopt HD Radio as a digital standard. But with HD ready new cars coming from the US hitting the roads here, the relatively late adoption, albeit experimental up to now, doesn’t face the “zero receivers” problem that the US struggled with 10 years ago.
2017 has turned into a “breakout” year for worldwide spread of the medium wave DRM digital standard. Recent successful trials in Indonesia, South Africa, Brazil and India coupled with commercial receiver introductions have given DRM a brighter future than it has seen in recent years. As reported here, India has the most aggressive roll-out of DRM deployment with six new Nautel high power transmitters shipped last month, bringing the total to 33 covering 92% of Indian territory and 99% of its population.

There is good news on the receiver side as well, with DRM capable receivers now appearing in passenger vehicles sold in India. Those receivers use a chip manufactured by NXP. Consumer receivers for DRM are also proliferating with a new mass produced table model by Gospell (China), the GR216, and an SDR model, the Titus II. At the upcoming IBC Show in Amsterdam (Sept 15-19), four DRM events are scheduled, including the first by a receiver manufacturer, Gospell, and an annual event sponsored by Nautel.
